UNITED S ATES HENRY ARTHUR DYGERT, OF PHILADELPHIA, PENNSYLVANIA.

ASSEMBLING monmn Application filed November 9, 1923. Serial No. 673,783.

To all whom it may concern:

Be it known that I, HENRY ARTHUR DY- GERT, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Assembling Machines, 'whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to machines for assembling the component partsof receptacles or containers made of sheet material, for example of the kind constructed of stout paper or card board for use'in dispensing dairy products or other liquid or semi-liquid food products. Such receptacles ordinarily comprise a body shell usually either of cylindri cal or conical form, and a circular member designed to serve as a bottom closure for the shell, the two members being permanently united by gluing or pasting.

The object of my invention is to provide a simple and eflicient machine which is continuous in operation and capable of assembling receptacles of the kind referred to with absolute accuracy and extreme rapidity.

In the drawings, Fig. I is a perspective view of an assembling machine convientlyembodying my invention.

Fig. II is a longitudinal sectional view of the same.

Fig. III is a cross sectional view of the machine taken as indicated by the arrows III-III in Fig. II.

Fig. IV is another cross sectional view taken as indicated by arrows IVIV of Fig. II.

Fig. V is an elevation of one end of the machine, showing more particularly the means whereby the conveyor is intermittently progressed.

Fig. VI is a detail view showing the means whereby the receptacle shells are initially engaged and placed in proper'position to be subsequently acted upon by the plunger devices which finally bring the two parts of the receptacles into the desired assembled relation.

Fig. VII is a view similar to Fig. VI showing the operation of the plunger devices aforesaid, and

Figs. VIII and IX are fragmentary detail views of the receptacle parts on a magnified scale showing more clearly the results of the operations of the machine.

As herein shown, the machine includes an endless conveyor comprehensively indicated by the numeral 1, comprising spaced parallel chains 22. These chains 2-2 are trained over sprocket wheels 34 respectively mounted in pairs upon shafts 56, supported in suitable bearings 7, at opposite ends of the machine frame generally indicated at 9. Extending transversely of the conveyor at regular intervals are cross-bars 10 that are secured at their oppositeends to the conveyor chains 22. As a means for preventing sagging of the conveyor in the space between the sprocket wheels 34, ways are provided for guiding the ends of the cross-bars 10, these ways consisting in the case of the upper run of the conveyor,

of parallel bars 11 12 suitably supported by brackets 13 atopposite sides of the machine, see Fig. III of the drawings. In the case of the lower run of the conveyor, the ends of the cross-bars 10 are sustained by a single longitudinal bar 14 at each sideof the machine, said bars 14 being held by gepending brackets. 15 of the machine frame Each of the cross-bars 10 supports a series of holders 16, (in the present instance four in number) which are preferably made conical so as to conform to the shape of the receptacles which are to be assembled. With the cross-bars 10, are individually associated channeled plates 17 whose side flanges 17 lap the side edges of said bars as shown in Fig. II. Each plate 17 is apertured to fit closely overthe holders 16 .and capable of limited free up and down move ment relative to the bar 10 the extent of this free movement being determined by headed studs 18. The plates 17 act in the capacity of strippers for dislodging the assembled receptacles from the holders 16 as will be more fully explained hereinafter. Intermittent movement is imparted to the conveyor by mechanism shown in Fig. V of the drawings as comprising aGeneva motion with a roller driving element 19 and the radially grooved follower 20. The latter or driven element 20 is secured directly to one end of shown) free on the sprocket shaft 6, but capable of being clutched with, or unclutched from a pulley 23, also free to re volve on said shaft and designed to be actuated by belt from any convenient source of power. Clutching and unclutching of the pinion to which reference has been made is controllable through operating connections which include, a shaft 24 extending longitudinally along one side of the machine and provided with one or more grasp handles 24 as shown in Fig. I.

Referring again to Fig. V, it will be noted that immediately adjacent the element 19 of the Geneva movement, 'the shaft 21 has mounted upon it a sprocket wheel 25 that is co-ordinatedby a chain 26 with a similar sprocket wheel 27 on a counter-shaft 28. As best seen in Fig. IV the shaft 28 has afiixed to it eccentric cams 29, which, by cooperation with anti-friction rollers 3031 secured to the upright end bars 32 of a vertically disposed frame 33 impart reciprocatory movement to said frame. This frame 33 is otherwise completed by a bar 34 which bridges the tops of the uprights 32. The

reciprocatory movements imparted to the frame 33 by the means just described are guided through sliding engagement of lugs 35 at opposite ends of the bridge bar 34 with fixed vertical rods 36 secured in standards or columns 37 rising from the frame work 9 of the machine.

Secured to the bridging bar 34 with ca- 38 comprises plunger disks 39-40, the latter being the larger of the two and overlying the first. In order to permit of relative adjustment the stem 41 of disk 39 has threaded engagement in the axial bore of the shank 42 formed integral with the disk 40, see Fig. VII. This disk-40 is provided adjacent its periphery with a circular series of apertures 40 which serve to relieve compression incidental to the operation of the plunger device 38. The desired adjustment of the disk 39 is fixed against being disturbed during the operations of the machine by a-set screw 43 provided for this purpose. Extending rearwardly from the top of the frame 33 are a pair of arms 45 whose extremities are .spanned by a transverse bar 46 that supports a series of depresser disks 47 spaced in acco rdance with the holders 16.

As a means for preventing bending of the cross-bars 10 under the action of the plunger devices 38, I employ mechanism including a roller 50 which is carried at the 11 per or free end of an arm 51 pivoted after t e manner of pen-knife blade about a fixed axis 52.- The arm 51 is normally held in the upright position shown in Fig. II by a helical spring 53 in tension between said arm and a fixed anchorage in the form of a bent wire anglebracket. 54 appropriately secured to the ma; chine frame. By this construction the arm 50-is permitted to yield automatically to permit passage of the flanges 17 of the channeled stripper plates 17 as the latter pass by during progression of the conveyor.

In order that the operation of the machine may be better understood, I will proceed first to describe the parts of the containers for the assembling of which the machine is designed, and also certain adjunctive devices useful in connection with the machine. From Figs. VI to IX inclusive, it will be noted that each receptacle comprises a shell S of frusto-conical configuration constructed of stout paper or flexible cardboard, and a base or bottom member B of similar material with a laterally turned circumferential flange F. For the purpose of stiffening the base or bottom member B and also for another reason which will become apparent later, the central portion of said member is raised or. embossed as indicated at It, and if desired, further rigidity may be had by employing a flat circular insert ,disk of somewhat stouter material such as indicated by the letter D. For convenience the machine is provided with a table 55 at one end upon which a supply of both the receptacle shells S and the bottom members B 'may be maintained and from which an operative may conveniently take the same and place them upon the holders 16. The machine is also provided with a bin 56 capable of being shifted beneath the run of the conveyorto receive the receptacles after assembling.

Preparatory to being placed in the machine, adhesive is applied about the inside of the smaller ends of the receptacle shells S at the region to be occupied by the flanges F of the bottom members B in assemblage. Such application may be effected by aid of any means suitable to the purpose as exemplified by the rotary gumming device comprehensively indicated by the numeral 56 in Fig. I of the drawings and shown as being driven by a belt 57 from a sheave 58 secured to the back face of the driving pulley 23.

The operation of the machine is as follows:

Assuming the motion of the conveyor to be that indicated ,by the arrows in Figs. I and II, the operative first places the bottom members B in inverted position uponthe tops of the holders 16, and then the shells S (after having been inserted into the gum cessively file past the table 55. \Vhen thus placed, it will be observed that the shells S are supported in suspension as a result of the restraint imposed to descent, by engagement of their sloping in sides with the circumferential flanges F of the members B initially counter flared as in Fig. VIII. In the course of the intermittent shiftings of the conveyor, the groups of holder 16 charged as just noted, come to rest successively beneath the depresser disks 4:7 and plunger devices 38. The movements of the frame 33 in definite correlation and correspondence with the movements of the conveyor result in the descent of the disks 47 upon the upper 'ends of the receptacle shells S thus depressing them relative to the members B supported on the tops of the holders 16 to an extent which will insure their entering beneath the I plunger devices 38. In the simultaneous descent of the plunger devices 38 upon the group of receptacle holders 16 immediately in advance of the larger disk L0 engages the upper ends of the receptacle shells S, further depressing said shells until the smaller disks 39 encounter the bottom members B. The .pressure exerted upon the bottom members B by the smaller plunger disks 39 causes the raised center portions R of said bottoms to be crushed, thereby expanding the flanges F so as to contact intimately with'the gummed inside surface of the container shells S. The cooperation of the flange disks 39 and 40 with the holders 16 thus results in bringing the shells S and the bottom members B into the desired assembled relation with the flanges F of said bottom members B flush with the top edges of the.inverted shells ny compression likely to result incidental-to the action of the plunger disks 40 is instantly relieved through the apertures 40 of the latter. As the .conveyor rounds the sprockets %1 at the delivery end of the machine, the stripper plates 17 fall away from the cross bars 10, automatically under gravity to the extent limited by. the stud bolts 18, and in so doing, dislodge the assembled receptacles S from the holders 16. Upon being thus released, the receptacles drop into the collecting bin 56.

Having thus described my invention, I claim: I

1.
